Diferentes sistemas de pontuação na pancreatite alcoólica aguda: qual a seguir? Um dilema em curso / Different scoring systems in acute alcoholic pancreatitis: which one to follow? an ongoing dilema

ABSTRACT BACKGROUND: Acute pancreatitis is a common disorder in medical practice. In recent times, management has changed drastically with majority of decisions like intravenous antibiotics, negative suction with Ryle's tube and surgical interventions like necrosectomy etc based on severity of the disease. There are different scores in use to assess severity of disease but the relative efficacy has remained a debatable subject. OBJECTIVE: The present study was thus done to investigate the predictive accuracy of different scoring systems in acute pancreatitis. METHODS: Fifty patients of acute pancreatitis admitted in medicine ward of Pt. B.D. Sharma PGIMS, Rohtak, India, were taken for study after fulfilling eligibility criteria. These patients were investigated at admission and followed up prospectively. The severity of pancreatitis was classified for each of these patients as per Revised Atlanta System of Classification. Commonly used scoring systems pertaining to acute pancreatitis, viz, BISAP, Ranson, APACHE II and modified computed tomography severity index (CTSI) were calculated. Subsequently these scores were then correlated with severity, presence of organ failure, occurrence of local complications and final outcome of the patients. RESULTS: Out of 50 patients, etiology was chronic alcohol intake in all but one with idiopathic pancreatitis. The mean age of the study population was 42.06±13.27 years. 32% of these patients had pancreatic necrosis, 40% had peripancreatic collections. 56% of them had mild acute pancreatitis, 24% had moderately severe acute pancreatitis, while 20% had severe acute pancreatitis. APACHE II had the highest accuracy in predicting severity, organ failure and fatal outcomes. As far as these parameters were concerned, the negative predictive values of BISAP score were also considerable. Modified CTSI score was accurate in predicting local complications but had limited accuracy in other predictions. CONCLUSION: APACHE II emerged as most reliable scoring system followed by BISAP and Ranson in management of the patients with acute pancreatitis. But in constraints of time and resources, even BISAP score with its significant negative predictive values served as a valuable tool for assessing and managing these patients.

RESUMO CONTEXTO: A pancreatite aguda é uma desordem comum na prática médica. Nos últimos tempos, sua gestão mudou drasticamente com a maioria das decisões tomadas baseadas na gravidade da doença, como administração de antibióticos intravenosos, sucção negativa com o tubo de Ryle ou intervenções cirúrgicas como necrosectomia, etc. Há diferentes escores em uso para avaliar a gravidade da doença, mas a eficácia relativa manteve-se um assunto discutível. OBJETIVO: O presente estudo foi assim realizado para investigar a acurácia preditiva de diferentes sistemas de pontuação na pancreatite aguda. MÉTODOS: Foram selecionados 50 pacientes com pancreatite aguda admitidos na enfermaria de medicina de Pt. B.D. Sharma PGIMS, Rohtak, Índia, e foram considerados para estudo após o cumprimento dos critérios de elegibilidade. Estes pacientes foram investigados na admissão e seguidos prospectivamente. A severidade da pancreatitie foi classificada para cada um destes pacientes pelo sistema de classificação Atlanta revisado. Os sistemas de pontuação comumente usados pertencentes à pancreatite aguda, ou seja, BISAP, Ranson, APACHE II e CTSI modificado foram calculados. Posteriormente, esses escores foram correlacionados com a severidade, presença de falência de órgãos, ocorrência de complicações locais e desfecho final dos pacientes. RESULTADOS: Dos 50 pacientes, a ingestão crônica de álcool foi a etiologia em todos, exceto em um com pancreatite idiopática. A média de idade da população estudada foi de 42,6±13,27 anos. Destes pacientes, 32% apresentavam necrose pancreática, 40% apresentavam coleções peripancreáticas, 56% apresentavam pancreatite aguda leve, 24% apresentavam pancreatite aguda moderadamente grave, enquanto 20% apresentavam pancreatite aguda grave. O APACHE II teve maior precisão em prever a severidade, a falha do órgão e resultados fatais. No que diz respeito a esses parâmetros, os valores preditivos negativos do escore BISAP também foram consideráveis. A contagem modificada de CTSI foi exata em prever complicações locais, mas teve a exatidão limitada em outras predições. CONCLUSÃO: O APACHE II emergiu como o sistema de pontuação mais confiável seguido por BISAP e Ranson na gestão dos pacientes com pancreatite aguda. Mas em condicionantes do tempo e dos recursos, mesmo a Pontuação do BISAP com seus valores preditivos negativos significativos, serviu como uma ferramenta valiosa para avaliar e administrar esses pacientes.

Acute-on-chronic liver failure: a new syndrome in cirrhosis

Patients with cirrhosis who are hospitalized for an acute decompensation (AD) and also have organ failure(s) are at high risk of short-term death. These patients have a syndrome called Acute-on-Chronic Liver Failure (ACLF). ACLF is now considered as a new syndrome that it is distinct from "mere" AD not only because of the presence of organ failure(s) and high short-term mortality but also because of younger age, higher prevalence of alcoholic etiology of cirrhosis, higher prevalence of some precipitants (such as bacterial infections, active alcoholism), and more intense systemic inflammatory response. ACLF is a new syndrome also because severe sepsis or severe alcoholic hepatitis do not account for 100% of the observed cases; in fact, almost 50% of the cases are of "unknown" origin. In other words, severe sepsis, severe alcoholic hepatitis and ACLF of "unknown origin" are subcategories of the syndrome.

Risk factors for nonalcoholic steatohepatitis in cryptogenic cirrhosis / Fatores de risco para esteatohepatite não-alcoólica na cirrose criptogênica

CONTEXT: In about 10% of patients with chronic liver disease, it is not possible to identify an etiologic factor. These cases are called cryptogenic cirrhosis. Currently, nonalcoholic steatohepatitis (NASH) is being considered as a possible etiologic factor for a significant segment of patients that presents with cryptogenic cirrhosis. OBJECTIVE: To estimate the prevalence of risk factors for NASH in patients with cryptogenic cirrhosis, in order to verify if there is a causal relationship between them. METHOD: Cross-sectional study, with evaluation of the demographic and laboratorial data of patients with cryptogenic cirrhosis. They were compared with data obtained from a group with NASH and a group with alcoholic and/or hepatitis C (HCV) cirrhosis. RESULTS: Forty seven patients with cryptogenic cirrhosis were evaluated, 47 with NASH and 196 with HCV and/or alcoholic cirrhosis. The mean age of patients with cryptogenic cirrhosis was 52 years, while in those with NASH it was 46.4 years (P = 0,041). The group with cryptogenic cirrhosis had 23 female and 24 male patients. Of the patients who presented with NASH, 68.1% were female. Of the patients who presented with alcoholic/HCV cirrhosis, 64.8% were male. There were no statistically significant differences between the groups. In cryptogenic cirrhosis patients, the following prevalences could be observed: impaired fasting glycemia - 68.2%; obesity - 27.5%; total hypercholesterolemia - 27.9%; low HDL levels - 58.1% (women - 81%; men - 36.4%); hypertriglyceridemia - 16.3%. The results seen in cryptogenic cirrhosis patients showed statistical similarity with the results of the NASH group regarding fasting glycemia (62.8%) and male HDL levels (53.8%). The comparison with the alcoholic/HCV cirrhosis group showed statistical differences regarding fasting glycemia (45.2%), hypercholesterolemia (13.3%) and female HDL levels (50.8%). CONCLUSIONS: It is not possible to establish a causal relationship between cryptogenic cirrhosis and NASH. Only data related to fasting glycemia and HDL levels in male patients showed statistical similarities between both groups of patients.

CONTEXTO: Em aproximadamente 10% dos pacientes com doença hepática crônica não é possível identificar um fator etiológico, sendo então rotulados como tendo cirrose criptogênica. Atualmente a esteatohepatite não-alcoólica (EHNA) tem sido considerada como provável etiologia em parcela significativa desses pacientes. OBJETIVO: Estimar a prevalência de fatores de risco para EHNA em pacientes com cirrose criptogênica com o intuito de verificar uma possível relação causal entre as duas doenças. MÉTODOS: Estudo transversal em que foi avaliado o registro de dados demográficos e laboratoriais de pacientes com cirrose criptogênica com a finalidade de compará-los com aqueles obtidos de um grupo de pacientes com EHNA e de um grupo controle composto de cirróticos por hepatite C (HCV) e/ou álcool. RESULTADOS: Foram avaliados 47 pacientes com cirrose criptogênica, 47 com EHNA e 196 com cirrose por HCV e/ou álcool. A média de idade dos pacientes com cirrose criptogênica foi 52 anos, enquanto a daqueles com EHNA foi 46,4 anos (P = 0,041). No grupo com cirosse criptogênica havia 23 mulheres e 24 homens. Naqueles com EHNA predominou o gênero feminino (68,1%) e nos cirróticos por HCV e/ou álcool predominou o gênero masculino (64,8%), sem diferença estatística entre os grupos. Naqueles com cirrose criptogênica, a prevalência de glicemia de jejum alterada foi 68,2%; obesidade, 27,5%; hipercolesterolemia total, 27,9%; baixos níveis de HDL, 58,1% (81% nas mulheres e 36,4% nos homens); e hipertrigliceridemia, 16,3%. A comparação com dados observados nos pacientes com EHNA mostra semelhança estatística entre o perfil glicêmico (62,8%) e níveis de HDL nos homens (53,8%). A comparação com os cirróticos relacionados ao HCV e/ou álcool mostra diferença estatística no perfil glicêmico (45,2%), colesterol total (13,3%) e HDL nas mulheres (50,8%). CONCLUSÃO: Não foi possível estabelecer uma relação causal entre a EHNA e a cirrose criptogênica. Apenas o perfil glicêmico e os níveis de HDL colesterol nos pacientes masculinos apresentaram semelhanças estatísticas entre os dois grupos de doentes.

The usefulness of transient elastography to diagnose cirrhosis in patients with alcoholic liver disease / 대한간학회지

BACKGROUNDS/AIMS: It is not easy to differentiate between patients with cirrhosis and those with alcoholic liver disease. Liver biopsy is generally considered the gold standard for assessing hepatic fibrosis; however, this protocol frequently carries a risk of severe complications and false-negative results. Transient elastography (Fibroscan, Echosens, Paris, France), which is a noninvasive method of measuring liver stiffness, has become available for assessing liver fibrosis. Liver stiffness reportedly differs markedly with the cirrhosis etiology. The aim of this study was thus to determine the diagnostic accuracy of the Fibroscan in the detection of cirrhosis in patients with alcoholic liver disease. METHODS: We enrolled 45 patients with alcoholic liver disease. Fibroscan, abdominal ultrasonography, aspartate aminotransferase/platelet ratio index (APRI), and liver biopsy were performed on all patients. Fibrosis stage was assessed using the Batts-Ludwig scoring system. RESULTS: The stage of fibrosis (F1-F4) was distributed among the cohort as follows: 5 patients at F1, 4 patients at F2, 7 patients at F3, and 29 patients at F4. Liver stiffness differed significantly between each fibrosis stage (P<0.001). For the diagnosis of cirrhosis, the area under the receiver operating characteristic curve was 0.97 for transient elastography (95% confidence interval, CI, 0.93-1.01), 0.81 for ultrasonography (95% CI, 0.68-0.94), and 0.83 for APRI score (95% CI, 0.70-0.95). The optimal cut-off value of liver stiffness for detecting cirrhosis was 25.8 kPa, with a sensitivity of 90% and a specificity of 87%. CONCLUSIONS: Transient elastography is a useful method for diagnosing cirrhosis in patients with alcoholic liver disease.

Hepatitis aguda alcohólica asociada a pancreatitis aguda grave / Acute alcoholic hepatitis and severe acute pancreatitis

Alcohol is a common cause of hepatic and pancreatic damage. Despite the widespread alcohol consumption simultaneous presentation of acute alcoholic hepatitis and pancreatitis is uncomnon. We describe a case of a patient with alcoholic hepatitis in association acute pancreatitis, who developed multiorgan failure and died. The association of liver and pancreatic disease in clinical practice is discussed.

El alcohol es un factor etiológico común de daño hepático y pancreático. A pesar de su extenso consumo la presentación simultánea de hepatitis y pancreatitis aguda alcohólica es excepcional. Se presenta un caso de esta situación, que evolucionó hacia la falla orgánica múltiple con desenlace fatal. Se discute la asociación de daño hepático y pancreático agudo en la práctica Clínica.

A Comparative Cross-sectional Study of the Development of Hepatocellular Carcinoma in Patients with Liver Cirrhosis Caused by Hepatitis B Virus, Alcohol, or Combination of Hepatitis B Virus and Alcohol / 대한소화기학회지

BACKGROUND/AIMS: Alcohol may be a cocarcinogen in patients with chronic viral hepatitis. We investigated the effect of alcohol on the development of hepatocellular carcinoma (HCC) in liver cirrhosis (LC) caused by hepatitis B virus (HBV). METHODS: All patients with LC or HCC associated with HBV or alcohol, admitted between March 2001 and June 2005, were included. Patients were divided into three groups according to the etiology of LC: Alcohol (AL), HBV, or HBV+alcohol (HBV+AL). Age and laboratory data at the enrollment of study were analyzed. The logistic regression coefficiency for the prevalence of HCC was calculated by using variables such as age, gender, serologic markers, and etiology of LC. RESULTS: In LC patients (n=342), the proportions of AL, HBV, and HBV+AL groups were 44%, 39%, and 17%, respectively. The proportions of HCC in AL, HBV and HBV+AL groups were 17%, 55%, and 76%, respectively. Age at the diagnosis of HCC was younger in HBV+AL than in AL group (p=0.036). In logistic regression analysis for the risk factor of HCC, odds ratio of age was 1.056 (p<0.001). Odds ratios of HBV and HBV+AL group comparing AL were 8.449 (p<0.001) and 17.609 (p<0.001), respectively. Therefore, old age and chronic alcohol intake in patients with HBsAg were the risk factors of HCC. CONCLUSIONS: Chronic alcohol intake may be an additive factor for the development of HCC in patient with LC caused by HBV. However, a prospective cohort study is needed to confirm these findings.

Non-hypertensive intracerebral haemorrhage: some interesting observations.

Hypertension is the commonest cause of intracerebral hemorrhage (ICH) but non-hypertensive intracerebral hemorrhages (NHICH) are not rare. We report three interesting cases of NHICH subsequent to amyloid angiopathy, alcoholic hepatitis and amphetamine abuse. They suggest the importance of recognizing these conditions and need for urgent specific therapy which may play a vital role in therapeutic planning and prevention of ICH.

Vibrio vulnificus: una causa infrecuente de shock séptico / Septic shock caused by vibrio vulnificus: report of 1 case

Vibrio vulnificus is a lactose positive Gram negative rod that lives in warm seas and can infect wounds and produce sepsis. Its infection is acquired after eating oysters or other filtering marine organisms. We report a 53 years old diabetic male who started with fever after a voyage to Central America. He was admitted febrile, hipotense, dehydrated and polypneic. Painful erythematous lesions and lumps were observed in his upper and lower limbs. After 72 hours of evolution, the lesions became violaceous, with crepitating vesicles full of hemorrhagic exudate. He developed a renal failure and a disseminated intravascular coagulation. Blood cultures demonstrated the presence of Vibrio vulnificus and the patient died 68 hours after admission

Presentaciones inhabituales de infecciones del tracto urinario en 6 casos / Unusual presentation of urinary tract infections in 6 cases

Urinary tract infections may have different clinical presentations that may range from asymptomatic bacteriuria to purulent collections and severe sepsis. We report 6 diabetic patients, 3 presenting with a renal carbuncle and 3 with an emphysematous pyelonephritis. All required medical and surgical treatment and had a good evolution. Two carbuncles were caused by beta-hemolitic type B streptococcus. This is the second notification of this agent as causative of renal abscesses, probably reaching the kidney through hematogenous dissemination from cutaneous foci
